What is the purpose of 40 CFR Part 503?

40 CFR Part 503 governs how sewage sludge, or biosolids, can be used or disposed. It sets the standards for sludge management, including options like land application, surface disposal, and incineration, and specifies limits on pollutants, as well as requirements for pathogen reduction, vector attraction reduction, and the management, testing, and reporting practices needed to protect soil, water quality, and public health. This is why the purpose is sludge use and disposal standards. Pretreatment standards (for industrial discharges to POTWs) fall under other regulations, New Source Performance Standards address air emissions, and water quality criteria are covered under other parts focused on ambient water quality.
